PotashStatistics and Information

Potash is used primarily as an agricultural fertilizer
(plant nutrient) because it is a source of soluble potassium,
one of the three primary plant nutrients; the others are fixed
nitrogen and soluble phosphorus. Potash and phosphorus are mined
products, and fixed nitrogen is produced from the atmosphere by
using industrial processes. Modern agricultural practice uses
these primary nutrients in large amounts plus additional nutrients,
such as boron, calcium, chlorine, copper, iron, magnesium,
manganese, molybdenum, sulfur, and zinc, to assure plant health
and proper maturation. The three major plant nutrients have no
substitutes, but low-nutrient-content, alternative sources of plant
nutrients, such as animal manure and guano, bone meal, compost,
glauconite, and "tankage" from slaughterhouses, can be used.
Potash denotes a variety of mined and manufactured salts, all
containing the element potassium in water-soluble form.
